[0033] Reference is made to the accompanying drawings Figure 3The mounting head 6 is mounted on the outer linear bearing of the unloading plate 4, and the unloading guide tube 5 is fixedly mounted on the inner side of the manifold 3. One end of the mounting head 6 is movably inserted into the inner cavity of the unloading guide tube 5.
